you're gonna need a special program to edit the files, i remember there was a video on youtube on how to do it but it looks like it has been deleted... i'll make a post detailing all the steps so that others can link to it. then i'll also post it here.
sorry if i've been inactive lately, been going through a lot and just came home today. will stay inactive in the next few days for other personal reasons. will try to answer any questions whenever i can though!
